PURPOSE Transforming growth factor-β-induced protein (TGFBIp) is highly expressed in the cornea, and mutant TGFBIp induces corneal diseases. However, the function of TGFBIp in cornea epithelium is not fully investigated. Here, we tested the importance of TGFBIp in regulation of gene expression and corneal epithelial cell (CEC) activity. MATERIALS AND METHODS The effect of TGFBIp on CEC activi...

Infection with intestinal nematodes induces profound pathological changes to the gut that are associated with eventual parasite expulsion. We have applied expression profiling as an initial screening process with oligonucleotide microarrays (Affymetrix MG-U74AV2 gene chips) and time course kinetics to investigate gene transcription triggered by the intraepithelial nematode Trichinella spiralis ...

Mucus hyper-secretion is a hallmark feature of asthma and other muco-obstructive airway diseases. The mucin proteins MUC5AC and MUC5B are the major glycoprotein components of mucus and have critical roles in airway defense. Despite the biomedical importance of these two proteins, the loci that regulate them in the context of natural genetic variation have not been studied. To identify genes tha...

the present study was conducted to test the effect of origanum majoranum extract (ome) of leaves on alterations induced in a model of type 2 diabetic rats. adult male wistar rats were fed high fat diet for 3 weeks and injected a single dose of streptozotocin (35 mg/kg) intraperitoneally to induce type 2 diabetic rats. diabetic rats were given aqueous extract of ome in a dose of 20 mg/kg orally ...

Mucin glycoproteins play a key role in the normal function of the airway epithelium. We examined the expression of mucin genes, MUC3, 4, 5AC, 5B, 6, 7, and 8 in human fetal tissues to establish the localization and age of onset of expression of each mucin gene during human development. We detected expression of MUC4, 5AC, 5B, and 7 in the mid-trimester airway epithelium but did not detect expre...

introduction: cryptorchidism has been proved to cause apoptosis in germ cells in respond to changes in the stimulation levels of specific physiological events. the purpose of this study was to determine whether treatment of bilateral cryptorchidism was associated with alterations in testicular gene expression. methods: to induce bilateral cryptorchid model, immature mice were anesthetized and a...

Antibodies provide a suitable tool in fundamental research and their high affinity and specificity make them invaluable for diagnostic and therapeutic applications. A promising alternative to conventional antibodies are the heavy chain antibodies (VHH) of Camelidae having short length, high solubility and stability are preferred to other antibody derivatives. In this study, our goal was product...

Mucus hypersecretion is characteristic of chronic airway diseases. However, regulatory mechanisms are poorly understood. Human airway epithelial cells grown on permeable supports at the air-liquid interface (ALI) develop a mucociliary morphology resembling that found in vivo. Such cultures provide a model for studying secretory cell lineage, differentiation, and function, and may provide insigh...

IMPORTANCE Chronic otitis media with effusion is characterized by middle ear secretion of mucin glycoproteins, predominantly MUC5B; MUC5AC, the other secretory mucin studied frequently, has also been identified in the middle ear. Emerging evidence suggests a dichotomous role for these mucins in innate immune responses. We hypothesized that MUC5AC is an acute responder and MUC5B is expressed at ...

Gram-negative bacteria can stimulate mucin production but excessive mucus supports bacterial infection and consequently leads to airway obstruction. Therefore the effect of dexamethasone (DEX) and the antioxidant acetyl-cysteine (ACC) on bacterial induced mucus expression was investigated. Explanted human airway mucosa and mucoepidermoid cells (Calu-3) were stimulated with lipopolysaccharide (L...
